Title: Dual dosing measurement and control device - maintains two-component dosing system dosage ratio within preset limits
Inventor: SZABO TIBOR DIPL ING
IPC: G05D11/13
Filed: 1976-10-05
Abstract: A measurement and control device enables dosage ratio control for a two-component dosage plant. It has two continuously operating dosing pumps whose pressure pipes are connected to a mixer whose mixture pipe leads to an output device. The device uses flow rate transducers and maintains the mixture ratio within permissible limits of deviation either side of a preset value. Flow rate transducers are placed in two of the three pipes and generate pulse signals proportional to the flow rate which are compared in a comparator. Pulse signals deviating from the preselected ratio are stored and when the deviation exceeds the selected limit a further signal pulse is generated.

Title: Electronic method of measuring nerve conduction speed - modifies and then repeats an unsuccessful attempt at measurement
Inventor: NETTELHORST HERWIG FREIHERR VO
IPC: A61B5/00
Filed: 1976-10-28
Abstract: An automatic indication of the speed of conduction along a nerve, as well as of the latent time, is obtained from an electronic interpretation of the EMG response signal. If the attempt at making the desired measurement does not succeed, the electronic interpretation is to provide a guide to the necessary corrective action. The electronic interpretation preferably indicates any manual operations required, or makes the necessary corrections automatically; preferably again, the electronic interpretation leads to repeated attempts at a successful measurement.

Title: Collision avoidance system for model railways - uses programmable memory with integrated circuit logic module for points setting
Inventor: JAEGER ANDREAS
IPC: B61L21/04
Filed: 1977-01-22
Abstract: The anti-collision signalling system for railway networks, esp. model railway layouts comprises a monitor associated with each set of points at the start or end of a length of track. The set position of these points provides a blocking signal for all other track sections associated with this set of points. The monitor is constructed from an integrated circuit logic module. A programmable memory is used to store the information relating to the straight or branch line settings associated with the sets of points to be traversed. The outputs of the memory give either logic high or logic low signals depending on whether the points are to be set for a straight-through or branching operation on a certain track length.

Title: Identification circuit for subscriber stations - has identification network delivering modulated DC signal containing subscriber numbers
Inventor: EISL ENGELBERT
IPC: H04Q3/00
Filed: 1977-09-30
Abstract: The identification is made on the ground of identification interrogation signals in telephone exchanges. AN identification signal is applied, as in circuit testing, through the interrogation switching element and the connection path already built-up to a device individually allocated to the subscriber, e.g. a subscriber circuit, and from there back through an identification network delivering the subscriber number to a transmitting device.

Title: Timing control for fuel pump - using angularly adjustable cam ring controlled by hydraulically actuated piston with pressure correlated with engine speed
Inventor: VARCOE ELLIS
IPC: F02M41/14
Filed: 1977-11-22
Abstract: The fuel injection pump includes a charge pump for delivering discrete pulses of high pressure liquid fuel sequentially tp the several cylinders of an associated engine and has an angularly adjustable cam ring to control the timing of the pumping strokes. The position of the cam ring is controlled by an advance piston, the position of which is controlled by a hydraulic pressure correlated with engine speed. A load sensing piston, engageable with one end of the advance piston above a fixed amount of timing advance, is subjected to the pressure of the metered fuel downstream of the metering valve. This controls the quantity of fuel delivered by the pump to urge the advance piston in a direction to retard the timing of the pumping strokes. This results in a timing control system in which the timing is more advanced at high speeds and light load than it is at high speeds and full load.
